I freeze an average of 8-10 dozen ears of corn every summer; it is our vegetable of choice, and we use it up before spring. I clean my corn, drop it into boiling water for 2 minutes, then plunge into ice cold water until it is cool. I stand the ears of corn in my dish drainer, until the water drains off, then put in gallon size freezer bags and stack in the freezer. Never had a problem with this method. The key to remember when you get ready to cook the frozen corn, is that it is already precooked, so I either steam it, or drop in boiling water for another 2-3 minutes.
